The concept of equity encompasses fairness and justice.
In their Healthy People 2020 report, the U.S. Department of Health and Human Services defines health equity as the "attainment of the highest level of health for all people. Achieving health equity requires valuing everyone equally with focused an ongoing societal efforts to address avoidable inequities, historical and contemporary injustices, and the elimination of health and health care disparities."
The DHHS defines a health disparity or inequality as "a particular type of health difference that is closely linked with social or economic disadvantage. Health disparities adversely affect groups of people who have experienced greater social or economic obstacles to health based on their racial or ethnic group, religion, socioeconomic status, gender, mental health, cognitive, sensory, or physical disability, sexual orientation, geography, or other characteristics historically linked to discrimination or exclusion."
